The function of conservator in a transformer is___________________?
Correct answer: D. to take care of the expansion and contraction of transformer oil due to variation of temperature of sur-roundings
- A. to project against'internal fault
- B. to reduce copper as well as core losses
- C. to cool the transformer oil
- D. to take care of the expansion and contraction of transformer oil due to variation of temperature of sur-roundings
Explanation
Transformer oil expands when heated and contracts when cooled. The conservator provides an oil reservoir to accommodate these volume changes while keeping the main tank filled.
